IMPROVEMENT IN MACHINES FOR MIXING BATCH FOR GLASS.

Specification forming part of Letters Patent N o. l {0,029, datedDecember 13, 1.570.

To all zij/71,0717, t may concern:

Be it known that I, WILLIAM T. GILLINDER, of the city of Philadelphia,in the State of Pennsylvania, have invented certain Improvements inMachines for Mixing Batch for Glass, of which the following is aspecification.

My invention relates to the combined arrangement of a close prismatic orcylindrical rotary case provided with interior-projecting ribs iixed inlongitudinal directions along its inner sides, with a rotary shaftprovided with rows of radial paddle-arms, and arranged to be rotatedwithin the rotary case in an opposite direction and at a more rapidspeed, and operating together in mixing therein the dry materials for abatch, in such a manner that the ribs of the case will successively tendto throw new portions of the loose material from one side of the casetoward the central shaft, while the rows of paddle-arms of the saidshaft tend to move the said materials in alternating longitudinaldirections within the case, the object of my invention being to producea machine that will, in operation, effect with facility and rapidity athorough or intimate mixture of the said dry materials required inymaking batch for subsequent melting into glass.

In the accompanying drawings, Figure l is a vertical longitudinalcentral section of my said improved mixing-machine, and Fig. 2 atransverse section of that part of the shaft and case on the right-handside of the dotted line o w of Fig. 1.

The shaft A, provided with its radial arms a a, rotates on its ownjournals a a within the journals b b of the case B, the same beingsupported in the uprights of the frame G in such a manner thatsimultaneous rotary motions may be given to both in opposite directionsby means of suitable gearing. Motion is given to the case B by means ofa large spur-wheel, D, on the main driving-shaft E,

(see Fig. 1,) which wheel D gears into a broad pinion, F, fixed on theshaft A, and motion in an opposite direction and slower is given to thecase B by means of a pinion, d', fixed to the wheel D, which pinion dgears into a large spur-wheel, G, xed on the journal b of the case B.The connected wheel and pinion D d are secured upon the shaft C by meansof a feather,77 so that the said wheel and pinion extend from end to endof the inside of the case, as represented in the drawings. The

arms a a are fiat tapering plates or blades,

fixed in the shaft A in longitudinal rows, projecting radially nearlyinto contact with the projections b, or so that as they are carriedaround by the shaft their ends will just clear the said projections. Thearms a are fixed perpendicularly in the shaft A, with their broad sidesarranged obliquely across the shaft, and those of each longitudinal rowobliqued oppositely in their relation to those of its two nearest rows.vided with three equidistant openings tted with adjustably-securedcovers 4 4 4, (see Fig. 2,) for more readily admitting and dischargingthe materials and batch.

The whole machine is intended to be made strong, to be driven by steamor horse power, and the case A capable of holding about one thousandpounds (more or less) of the dry sand, powdered soda, lime, Src.,required to make a batch for melting into glass.

Operation: About five hundred pounds of the materials, consisting of thesand, pulverized soda, lime, &c., having been successively thrown intothe case B and the case closed, the machine is to be putin motion, thuscausing a slow and regular rotary motion of the case B, and a more rapidrotary motion, in an opposite direction, of the sh aft A, and the casebeing only about half full the contents are c011- tinually beingcommingled by the j oint operation of the two parts, the projections orribs b of B successively elevating and discharging` new portions of thecontents along one side of the case, and the rows of arms a of itrapidly and continuously agitating and moving the said contentspromiscuously from end to end within the case. A thorough or intimatemixture of the :Inaterials contained in the case B is thus effected inabout five or sin minutes,

whereas by the old mode of mixing batch by The shell of the case B ispro- Shovel in hand the Vtime and labor required l are enormouslygreater and the mixing never perfect. After the Contents of the ease aremixed perfectly, the double wheel D d is to be slipped forward on itsshaft E, so as to disconnect it from the wheel G, and thus stop therotary motion of the ease. The cover nearest to the under side is thenremoved and the contents run out into a pit or any suitable re; ceiver.

I claim as my invention- The combined arrangement of the case B, shaftA, and their respective attachments b and a', constructed and operatingtogether substantially as and for the purpose hereinbefore set forth anddescribed.
